There are many, many quilt designs that take the name kaleidoscope. Ricky Timms sells a DVD and pattern for his 'Kool Kaleidoscopes'. Stack-n-whack designs are frequently referred to as kaleidoscopes, as are OBW's. And there are tons of traditional block designs with that name. Morningcoffeegal gave you several examples. Is there a particular quilt that you want to duplicate? If we see a picture that would help to narrow down your search.
